meaning of oesophagus,ingestion
Answers
Answer:
The oesophagus is a muscular tube, about 25cm long, with a sphincter (valve) at each end. Its function is to transport food and fluid, after being swallowed, from the mouth to the stomach. No absorption of nutrients takes place in the oesophagus. A mouthful of food which has been chewed and swallowed is called a bolus.
Ingestion is the consumption of a substance by an organism. In animals, it normally is accomplished by taking in a substance through the mouth into the gastrointestinal tract; such as through eating or drinking.

the mouth and when swallowed passes first into the pharynx and then into the esophagus. The esophagus is thus one of the first components of the digestive system and the gastrointestinal tract. After food passes through the esophagus, it enters the stomach.
